Is this product the right choice for you?
Honestly, no pressure. Decide once — and get it right.
✅ Best suited for
The Cybex Sirona G3 i-Size is an excellent choice for parents looking for one seat for a long period – from birth (with the additional newborn insert) up to approximately 4 years of age or 105 cm in height. We especially recommend it to those who value rear-facing travel, as it offers significantly greater safety in a frontal collision. The 360° rotation makes it easier to place your child in the car, while the improved L.S.P. protection provides additional safety in a side impact.
🤔 Less suitable if
The seat isn't suitable for immediate use without the Base G3, which needs to be purchased separately, and you'll also need an additional infant insert for a newborn. It's also less suitable for parents looking for a seat that can be installed with just the car seatbelt, since it's designed for use with an ISOFIX base.
